Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588556, here are decompositions:

73 + 31588483 = 31588556
157 + 31588399 = 31588556
199 + 31588357 = 31588556
577 + 31587979 = 31588556
607 + 31587949 = 31588556
613 + 31587943 = 31588556
739 + 31587817 = 31588556
757 + 31587799 = 31588556

Showing the first eight; more decompositions exist.
